Assign an OSPFv2 area, Enable OSPFv2 on Interfaces, In CONFIGURATION ROUTER OSPF mode

Page 371 highlights

In CONFIGURATION ROUTER OSPF mode, assign the Router ID. The Router ID is not required to be the router's IP address. For easier management and troubleshooting, Dell Force10 recommends using the IP address as the Router ID. Command Syntax router-id ip address Command Mode Usage CONFIG-ROUTER-OSPF-id Assign the Router ID for the OSPFv2 process. IP Address: A.B.C.D To disable OSPF, use the no router ospf process-id command in CONFIGURATION mode. To reset the OSPFv2 process, use the clear ip ospf process-id command syntax in EXEC Privilege mode. Assign an OSPFv2 area After you enable OSPFv2, assign the interface to an OSPF area. To set up OSPF areas and enable OSPFv2 on an interface, use the network command. You must have at least one AS area: Area 0. This is the backbone area. If your OSPF network contains more than one area, you must also configure a backbone area (Area ID 0.0.0.0). Any area besides Area 0 can have any number ID assigned to it. The OSPFv2 process evaluates the network commands in the order they are configured. Assign the network address that is most explicit first to include all subnets of that address. For example, if you assign the network address 10.0.0.0 /8, you cannot assign the network address 10.1.0.0 /16 because it is already included in the first network address. When configuring the network command, you must configure a network address and mask that is a superset of the IP subnet configured on the Layer-3 interface to be used for OSPFv2.

Open Shortest Path First (OSPFv2)
|
369
In CONFIGURATION ROUTER OSPF mode, assign the Router ID. The Router ID is not required to be
the router’s IP address. For easier management and troubleshooting, Dell Force10 recommends using the
IP address as the Router ID.
To disable OSPF, use the
no router ospf
process-id
command in CONFIGURATION mode.
To reset the OSPFv2 process, use the
clear ip ospf
process-id
command syntax in EXEC Privilege mode.
Assign an OSPFv2 area
After you enable OSPFv2, assign the interface to an OSPF area. To set up OSPF areas and enable OSPFv2
on an interface, use the
network
command.
You must have at least one AS area: Area 0. This is the backbone area. If your OSPF network contains
more than one area, you must also configure a backbone area (Area ID 0.0.0.0). Any area besides Area 0
can have any number ID assigned to it.
The OSPFv2 process evaluates the
network
commands in the order they are configured. Assign the network
address that is most explicit first to include all subnets of that address. For example, if you assign the
network address 10.0.0.0 /8, you cannot assign the network address 10.1.0.0 /16 because it is already
included in the first network address.
When configuring the
network
command, you must configure a network address and mask that is a superset
of the IP subnet configured on the Layer-3 interface to be used for OSPFv2.
To set up each neighbor and OSPF area, use the following command in CONFIGURATION ROUTER
OSPF mode. The you can assign the area by a number or with an IP interface address.
Enable OSPFv2 on Interfaces
Each interface must have OSPFv2 enabled. It must be configured for Layer 3 protocol and not be
shutdown. OSPFv2 can also be assigned to a loopback interface as a virtual interface.
